Hello and welcome back for another review. This time I was sent the YiHi SXmini MQ Class mod by Sourcemore in order to provide you with a fair and honest review. The MQ is a very compact mod that uses a single 18650 battery for an output range of 1-60 watts. It can fit a tank up to 24mm without any overhang and is made of stainless steel and aluminum via a CNC process. The output voltage is 1-8V so it is obviously boosting the output voltage.
WHAT’S IN THE BOX?
1* SXmini MQ Class Device
1* User Manual
1* Type-C USB Cable
1* Warranty Card
SPECIFICATIONS:
FEATURES:
1. Small grip
2. Up to 24mm for wide selection of atomizers
INITIAL THOUGHTS:
I was really surprised by how small the box is for the MQ. I thought that if the box is this small then the mod had to be really small and it is. The front of the box has both the SXmini and the MQ Class names printed on the front along with a large warning on the bottom. I personally think this warning is ridiculous as everyone knows that there isn’t any nicotine in a mod but the manufacturer is just following the required laws. The back of the box has a contents list, some features, and a second large warning.
Once the box is opened, the MQ is visible and there is a USB cable, user manual and warranty card. I have to hand it to SXmini when it comes to the user manual. It is probably one of if not the best manuals that I’ve seen. You can see in the picture below that the nice sized fire button is located on the wider side of the mod instead of the end like we see on many mods. Below the fire button is the display screen which I will cover in detail later, followed by the + and – buttons.
In the second picture you can see the MQ beside the Gen SE which is also an 18650 mod. The MQ is much shorter and a bit less wide. The third picture also shows the mirrored center strip on the back side of the MQ with MQ Class etched into it.
The MQ can fit an atomizer with a base of up to 24mm without overhang which is really good in my opinion for such a small device. The top plate is held in place with two torx head screws. The 510 center pin is plated and spring loaded. There are four airflow channels cut into the top plate. It is my understanding that some older tanks actually drew airflow from the 510 connection so those would work on this mod. Also I think the cut outs look cool.
The MQ makes use of a threaded screw in battery cap like many mods are using these days. The cap is partially open which would allow for battery venting should something happen. The base is also held in place with two torx head screws like the top plate. The plate has the SXmini and MQ Class names etched on it. In the second picture below you can see that battery polarity is clearly marked inside the compartment with a large red +. The threaded cap has a raised center to help make contact with the battery negative. The bottom plate also contains the USB-C charging/update port. One thing to take note of is that if you charge the battery in the mod then it will automatically reset the puff counter so if the count is important to you then you will want to use an external charger. It seems like a really odd feature to me.
The display screen for the MQ is pretty basic. It has a battery level indicator, puff counter, set wattage, coil resistance, and output voltage. The MQ has a maximum output voltage of 8 volts. I really don’t mind the simplistic display. Normally I set the wattage for the tank I am using and don’t really change it or look at the display much except for the occasional glance to see where the battery level is.
The button/menu operation for the MQ is as follows.
FINAL THOUGHTS:
I have really enjoyed testing the SXmini MQ Class Mod. I very much like the small size of the mod that almost disappears in the hand. The basic display and easy to operate menu system is nice in a world of way too complicated operating menus that some mods have. It is small but has a feeling of quality being made of good materials. I don’t mind the limited 60 watt maximum output. I tend to use small mods like this with MTL tanks and the 24mm atomizer capacity is a good fit. I ran the Hellvape Dead Rabbit MTL 2 tank during my testing with one of my favorite NET tobacco mixes. The battery management seemed very good and ran almost 400 puffs with the wattage set at 23w. I really don’t use any modes besides wattage on any of my mods but it is nice that the MQ can do TC, Curves, and has VT Coil mode if that is something that you like to use. VT Coil mode is a dry hit protection mode intended for use only with VT coils. I didn’t have any for the review so wasn’t able to test that.
I’d like to thank Sourcemore for sending the SXmini MQ Class Mod for this review. Also a big thanks to the readers. Below is a link to the website for your viewing pleasure as well as a discount code.
